Run the test again. I have never received same numbers in any invocation of HDD Scan.

I doubt you can find bad sectors with new drives any more from windows. They get remapped by the firmware when they are encountered. Appropriate counters are incremented in SMART. HD Sentinel is a useful tool for interpreting SMART values.

If you think some parts are about to fail, run a full format from disk management in windows and it will have the drive remap failing sectors.

And inspecting the log, I suspect the slow sectors are concentrated in one platter.

I think one of the three platters is "sub-standard".

I got basically the same result before and after formatting.

I did a long formatting using Windows XP.

To make things worse, the shop has not answered my mail in the last 24 hours.

They told me that if the Samsung diagnostics fail, then my drive will be exchanged without problems. But I told them that the drive passes it because this utility doesn't detect slow sectors.

Of course, this is a bit absurd: just imagine you get a drive with heavy external damage, but it passes Samsung diagnostics... according to this logic, the drive can't be returned???

How are you testing this drive? Is it the boot drive? If not, can you move it to another controller? For example, if you have Jmicron or some other controller on the board other than intel, can you connect it to that one and run the test there?

If it is the boot drive, can you make sure the system is idle (no indexing, a/v, etc running at the back ground). Even if it is on a seperate controller or if it is a seperate drive, make sure nothing is doing any disk intensive operations on your boot drive. I have awful results whenever there is disk operations on my boot drive (even though the drive being tested is on a seperate port or controller).

I will post you some screenshots later so that you can see what i mean.

Did you run HD Sentinel on this drive and examine smart values?

If nothing works and they do not accept the drive back, just short circuit it and let it die. Dirty, unethical, yes... but sometimes the only solution to get your right back since this drive is faulty and you paid for it.

For example, if i am running HDDScan and i start Everest from my boot drive, i immediately get few orange sectors. Taht is probably Everest is querying the drive for SMART info. It is important those tests are done on a clean system with no software running.

I hate that i cannot edit anything after few seconds in this forum. At least make it 5 mins or something.

>>Where did they go? It was half a million, now they are 1700? Is the HDDScan or HDTune graph still erratic?

I think the old version reports the "gray blocks" incorrectly (<50ms).

As you see, the (<15ms) was zero in the old version.

But the green blocks (<150ms) is quite consistant.

The shop has finally answered. They say that Samsung won't exchange a disk just because of slow sectors. They say that under 500ms is not a problem!!! Just imagine the case of a brand new disk full of 500ms sectors and I can't return it !!

I am going to insist diplomatically. If this doesn't work, I will use other methods.

Did you consider using it for offline storage/backups? I mean, fill it up with stuff, do md5 checksums of the files, and if no errors, just take the drive offline with your data. Its health would not detoriate if it will not be used.
